Remote Audio BDSv5 SMART Manual

BDSv5 SMART
The BDSv5 SMART is the next generation of the Remote Audio BDS, the
standard in power management systems for ENG audio bags. It is a 12V
nominal compact DC power distribution system that now features dual
power inputs that allow for battery hot swapping as well as input priority
and load sharing for higher current draw conditions. It incorporates
System Management Bus (SMBus) communications and a built in 0.95"
color OLED display for detailed usage and runtime statistics when using
smart batteries equipped with internal Battery Management Systems
(BMS) such as Remote Audio's HI-Q 49Wh and 98Wh batteries.
Additionally, the BDSv5 SMART has been expanded from 6 to 8 outputs
and is available with 2 output connector variants: Standard (5.5mm barrel jack) and Hirose (4-pin).
Inputs: The BDSv5 SMART's dual TA4-pin inputs can accept various types of batteries and DC input sources ranging from
9-18 Volts DC. The dual inputs feature an integrated power path controller meaning you no longer need to shut down
critical gear when it comes time to change out a depleted battery pack. Simply remove one of the batteries from its
corresponding battery cup and pop in a fresh one while the other battery will maintain an uninterrupted* output. The
power path's interconnected ideal diode controllers prevent reverse current flow from one battery into the other.
*The total load on the BDS must be less than a single battery's rated max discharge current to perform hot swaps.
Priority Input: A new feature to the BDSv5 is input priority. When enabled in the settings menu, the BDS will prioritize
drawing power from Input #1 while Input #2 goes into standby. This allows you to prioritize using say an AC to 12V DC
adapted power supply plugged into Input #1 while conserving a 14.4V smart
battery plugged into input #2. If the voltage of Input #1 falls below a threshold,
the BDSv5 will automatically failover to the second input for uninterrupted
power output. Once power is restored to Input #1, it resumes its priority role for
powering the load and Input #2 will go back into standby. It should be noted that
a battery in standby will still have a very small current draw on it from the
battery communications and microprocessor of the BDSv5 so it is normal to see a
battery in standby discharge slowly over time.
Load Sharing: Another new feature of the BDSv5 is a load sharing function
between two batteries whereby you can power loads that draw more current than a single battery pack is capable of
supplying by itself. For example, two HI-Q 49Wh, 3.4Ah batteries could supply up to 6.8Amps when load sharing, and two
HI-Q 98Wh, 6.8Ah batteries could supply up to the BDS's limit of 12 Amps total current when load sharing. To enable load
sharing, you must turn off the Priority #1 setting in the settings menu. For best performance when load sharing, it is
recommended to always use two batteries of equal capacity and similar states of charge. These features greatly expand
the BDSv5's useability from ENG bags of all sizes to small and even mid-sized cart systems.
Output Current Limit: Since the BDSv5 can accept multiple battery capacities and DC sources, the BDSv5 Smart employs
a dynamic current limit and warning system. The maximum total load current handling of the BDSv5 is 12 Amps.
However, depending on what the input source type is or whether you have just one input active, a lower current
limitation and warning could be imposed. By default, any non-smart battery or DC input source is limited to 6 Amps (per
TA-4 input). Smart batteries capable of BMS communications will be limited to a 1C maximum discharge rate for safety.
1C is a rate of 1 times the battery's capacity so for a 49Wh battery with a capacity of 3.4 Amp hours, it would be limited
